Rails + Elastic Beanstalk + Passenger: change Passenger configuration

Question

I have a Rails (4.0.13 with Ruby 2.2.3) Elastic Beanstalk app with Phusion Passenger as its application web server.

I'd like to change some of the Passenger config variables. As stated here https://www.phusionpassenger.com/library/config/standalone/intro.html#location-of-passengerfile-json, I need to put a Passengerfile.json in the app root directory.

However, according to this post https://forums.aws.amazon.com/thread.jspa?threadID=181591, it makes no difference to put the config file there. That, and the fact that I cannot seem to check the passenger variables (passenger-status doesn't allow me and suggests sudo, but with sudo it says sudo: passenger-status: command not found) has prevented me from trying to put the config file there.

So, how can I check and change the Passenger configuration values?

Thanks!

Instead of using a file named Passengerfile.json you have to call it passenger-standalone.json, for example if you want to change max_pool_size you need a file with this content:

{
  "max_pool_size": 3
}

To check the status of the passenger process you can use passenger-status command but you have to use sudo with option -i to let root inherits your user's environment settings.

sudo -i passenger-status

Just a heads up, but passenger-standalone.json is now Passengerfile.json in version 5. See release notes – Sendoff
